Description

Technical Field

[0001] This utility model relates to the technical field of power cord protection devices, and specifically to a power cord protection device. Background Technology

[0002] Power cords are wires that carry electric current. Current is typically transmitted point-to-point. Power cords can be categorized by their application into AC (alternating current) power cords and DC (direct current) power cords. AC power cords usually carry higher voltage alternating current; due to the higher voltage, these cords require standardized safety certifications before they can be manufactured. DC cords, on the other hand, primarily carry lower voltage direct current, so their safety requirements are not as stringent as AC cords. However, for safety reasons, various countries still require standardized safety certifications.

[0003] A search revealed a utility model patent with publication number CN207217882U, which discloses a power cord protection device. The device includes a waterproof protective box, indicator lights, a switch, a label, a protective shell, status lights, a connecting tube, and a connecting plug. The waterproof protective box and the protective shell are connected by an interference fit, with the waterproof protective box nested on top of the protective shell. The indicator lights and status lights are embedded in the outer surface of the protective shell, with the indicator lights connected to the side of the status lights via the protective shell. The label and the protective shell are integrally molded, with the label located on the upper right side of the protective shell. The switch is embedded in the protective shell, and the connecting tube is embedded in the middle of the left side of the protective shell, connecting the connecting plug to the protective shell. The waterproof protective box consists of a fixing block, a protective cover, side plates, and a lifting buckle. The fixing block connects the side plates and the protective cover together. This utility model enables the power cord protection device to isolate the switch and other components from the air during use, reducing the occurrence of water ingress and leakage, and improving safety.

[0004] The aforementioned patents merely isolate switches and other components from the air during use through a waterproof protective box, reducing the occurrence of water ingress and electrical leakage, and improving safety. However, they cannot adequately address the issues of knotting and tangling that can occur during the storage of connecting wires, making safe use inconvenient. Furthermore, the lack of an auxiliary fixing structure makes it difficult to place the device, reducing its practicality.

[0005] Therefore, it is necessary to invent a power cord protection device to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a power cord protection device. Through the design of a winding reel and a cord limiting groove, the connected cord can be wound and stored. A spring-loaded auxiliary cord clamping block can be used to press the wound cord firmly, preventing loosening and achieving excellent cord management and protection. By rotating the rotating hook outside the storage groove and using a positioning block for insertion and fixation, along with hanging holes, the device can be suspended, improving practicality. By embedding magnets on the outside of the protective cover, the device can be easily fixed to a metal cabinet, effectively preventing it from being dragged off. This addresses the problems of existing technologies that cannot adequately solve the issues of knotting and tangling during cord storage, hindering safe use, and the lack of auxiliary fixing structures, which makes placement difficult and reduces practicality.

An operating block penetrating the limiting cavity is fixedly connected to the front side of the limiting block. A positioning block penetrating the power supply unit is fixedly connected to the side of the limiting block away from the second spring. The positioning block matches the positioning groove. Protective covers are hinged to both the front and rear sides of the power supply unit. Magnets are fixedly embedded on the relatively close sides of the tops of the two protective covers, and the two magnets cooperate with each other.

[0008] Preferably, a power cord that passes through the winding spool is fixed to the side of the power device body, and a power plug is fixedly connected to the end of the power cord.

[0009] Preferably, the connection between the power cord and the winding reel is fixedly fitted with an anti-bending sleeve.

[0010] Preferably, a power switch is embedded and fixed on the top of the power supply unit, a power indicator light is fixed on the top of the power supply unit, an interface status light is fixed on the top of the power supply unit, and a label description area is fixed on the top of the power supply unit.

[0011] Preferably, the power supply device body has two-pin input ports, one-pin input ports, and a USB input port embedded on both the front and rear sides.

[0012] Preferably, a two-pin input port is embedded on the side of the power supply unit away from the winding spool.

[0013] Preferably, a metal frame is uniformly fixed to the side wall and top of the protective cover.

[0014] Preferably, a magnet is fixedly embedded on the outer side of the protective cover.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] The connection of the wires is achieved by using a winding reel and wire limiting groove, allowing the wires to be wound and stored. The spring-loaded wire clamping block can be used to press the wound wires firmly to prevent them from loosening, thus providing excellent wire management and protection. The rotating hook is rotated outside the storage groove and fixed by inserting a positioning block. The device can be suspended by hanging holes, improving its practicality.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-7 The power cord protection device shown includes a power device body 1, a winding disc 2 fixedly connected to the side of the power device body 1, and a wire limiting groove 3 opened on the winding disc 2. The wire limiting groove 3 is used to repeatedly wind the excess wire that is connected to the two-pin input port 13, the three-pin input port 14, and the USB input port 15 to avoid knotting when storing and to extend the life of the wire.

[0029] A wire clamping block 4 is hinged to the top of the power supply unit 1. The wire clamping block 4 extends to the winding spool 2. A spring 5 is fixedly connected between the bottom of the wire clamping block 4 and the power supply unit 1. The elasticity of the spring 5 keeps the wire clamping block 4 pressing the wire in the wire limiting groove 3, limiting the winding wire and preventing it from loosening.

[0030] The winding reel 2 has storage slots 21 on both the front and rear sides. A rotating hook 22 is hinged inside the storage slot 21. The rotating hook 22 is then pulled into the storage slot 21 by the rebound of the torsion spring 24 for storage, so as to avoid taking up extra space.

[0031] The rotating hook 22 has a hanging hole 23 inside, which supports vertical hanging and makes it easy to store and place.

[0032] A torsion spring 24 is fitted at the connection between the end of the rotating hook 22 and the storage groove 21. A positioning groove 25 is provided on the side of the rotating hook 22. Limiting cavities 26 are provided on the front and rear sides of the power device body 1. A limiting block 27 is slidably installed inside the limiting cavity 26.

An operating block 29 that penetrates the limiting cavity 26 is fixedly connected to the front side of the limiting block 27. A positioning block 30 that penetrates the power device body 1 is fixedly connected to the side of the limiting block 27 away from the second spring 28. The positioning block 30 matches the positioning groove 25. The expansion of the second spring 28 keeps the positioning block 30 in the insertion state with the positioning groove 25, which is used to position the rotating hook 22 in use and facilitates hanging.

[0033] The power supply unit 1 is hinged with protective covers 17 on both the front and rear sides. Magnets 18 are fixedly embedded on the relatively close sides of the top of the two protective covers 17. The two magnets 18 cooperate with each other. The two protective covers 17 can protect the interfaces on the front and rear sides of the power supply unit 1 from dust and water. They can also be fixed by magnetic attraction of the two magnets 18, thus stabilizing the protective effect.

[0034] A power cord 6 that passes through the winding reel 2 is fixed to the side of the power supply unit 1, and a power plug 7 is fixedly connected to the end of the power cord 6.

[0035] A bend-resistant sleeve 8 is fixedly fitted at the connection between the power cord body 6 and the winding reel 2. The bend-resistant sleeve 8 is installed at the part of the power cord body 6 that is prone to bending and wear, thus extending its service life.

[0036] A power switch 9 is embedded and fixed on the top of the power supply unit 1.

The power supply unit 1 has two-pin interface 16 embedded on the side away from the winding disc 2. Multiple interface styles are set to improve the functionality and practicality of the device.

[0038] Metal frames 19 are evenly fixed to the side walls and top of the protective cover 17. The metal frames 19 can improve the structure and support strength of the protective cover 17, prevent damage from heavy objects, and improve the overall pressure resistance of the power supply device 1.

[0039] A magnet 20 is fixedly embedded on the outside of the protective cover 17. The magnet 20 can be used to magnetically fix the device to the metal cabinet, making it easy to hang and use, and preventing it from being dragged off.

[0040] The working principle of this utility is as follows: Connect the power plug 7 to the main power supply. When the power supply body 1 is needed, separate the two protective covers 17. The magnet 20 on one of the protective covers 17 can be used to magnetically fix it to metal furniture or objects to prevent the power supply body 1 from falling off due to subsequent dragging. Turn on the power by switching on the power switch 9. Then you can choose to use the two-pin connector 13, the three-pin connector 14, the USB connector 15, and the two-pin connector 2 16. After connecting, the cable can be wound along the cable limiting groove 3. After winding, it can be pressed tightly by the cable clamping block 4 to prevent loosening.

[0041] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
